Haltech HT-231801 Nexus Plug-In ECU – Nissan Skyline R32/R33/R34 GT-R & GTS-T

Suits: Plug 'n' Play replacement of the factory ECU for Nissan Skyline R32 GTS-T, R32 GT-R, R33 GTS-T, R33 GT-R and R34 GT-R. Manual transmissions only.

The Haltech Nexus Skyline Plug-in connects directly to the factory Nissan harness and mounts in the factory ECU location. It retains vital OEM functions including the R34 GT-R MFD injector duty cycle display and GT-R ATTESA TPS output, while unlocking "OEM Plus" capability via the auxiliary connector — closed loop O2 control, flex fuel, oil and fuel pressure monitoring, and drive-by-wire throttle support.

For serious drivers, the Nexus platform adds full race functionality: CO2 boost control, race timer, advanced torque management, launch control, nitrous control and 128MB of onboard data logging. Setup is quick with the wizard in Haltech's NSP software or the Haltech Connect smartphone app, with onboard Wi-Fi for wireless diagnostics and tuning.
